Simple question for you guys, and I'm pretty sure the answer's "no", but thought worth asking regardless:
I am using addline in my mapscript to create some road segments. However, for each of my road groups, I want to have one of the modules only appear once, not any number of times as can happen currently. E.g. RXRRRR where R is the regular road tile and X is a car pileup. Multiple car pileups in a row would look a bit silly.
Is there a way to do this elegantly? Or do I have to make a large number of conditional addblock commands?
